Attendees listen to a presentation on barley markets at GrainWorld 2011.

The changes to the Canadian Wheat Board's marketing system are having a number of ancillary impacts.

The CWB has announced it will not be hosting the GrainWorld conference in 2012.

The event brought together grain industry leaders on an annual basis in late February to discuss marketing and logistical issues.

A number of other potential hosts have been identified and there's hope the conference can resume in 2013.
